Pam, this one:
8/25- Daytrip, Pompeii & Herculaneum
IMHO, too much for one day, especially in August heat. Pompeii is VAST and there's very little shade. It's not impossible to do both but given the size of Pompeii and the amount of information there to absorb, if really interested in the site, I think you'd be all in by the time you're through. We did it last time in early October and it was plenty warm THEN; spent 5 hours (not including time to and from the scavi) and still didn't cover it all. Some folks only spend 2 hours but will only see a fraction of what's there. An idea of just how large it is?

A comprehensive guide you can use for boning up before or for reference during your visit:

And another page which may be useful; it may not be 100% current as closures of individual structures can occur at any time:

All are from the OFFICIAL website for the scavi. :O)
And just a personal take on this one?
8/27-28- Overnight trip to Capri & Ischia: 8/27- Blue Grato
Capri's Blue Grotto is the closest thing to a tourist trap on the island. It can eat a lot of time/$$ for the few minutes you're in the thing (if the sea cooperates enough to even get into it) and reports have been many of the boatmen hassling visitors for tips. I also read that it's not a great choice for anyone with motion sickness; all the bobbing around in the rowboats prior to entry can be tough on touchy stomachs. Do it if you must but we skipped it during our two nights on the island and didn't feel we'd missed anything. Obviously, some folks enjoyed it so, again, just my IMHO.

Lots of better things to do, and you don't really need tours for most explorations. We did a lot of trekking about on foot to interesting spots:
